Azriel has little shadows that he can control and he can also blend in with. His shadows could catch the balls and throw them for him or he could teleport to his shadows for a quick escape. Azriel has quick reaction skills and can do quick problem solving when it comes to battle stuff, so I would want him as a defensive player.
I watched Twilight when I was younger and all I remember is that the vampires playing baseball and are super fast. I chose Edward because it was honestly the first person I thought of because I have that baseball scene weirdly engraved in my brain. He's just super fast and good at sports I'm assuming, so my defensive player.
I think Elastigirl would be the best player on this team because she can make herself into any shape and is extremely felxible. She could throw the ball right at the division line while standing in the far back. Elastigirl would be my team captain because I think she could handle dealing with these men.
Geralt from Rivia but specifically played by Henry Cavill. Geralt is scary strong and also when he drinks his witcher potion, he gets faster and stronger so I would hope that he can be a good attacker on the team. I also think it would be funny to watch him play dodgeball.
Draymond Green would be my secret weapon. He's got a big wingspan which makes me think he can throw far, which aside from the fact that he is an NBA player, it makes sense in my head. Since he's a forward player I think he'd be on the front lines aggressively throwing which I would hope, scare the other team.
